ABSTRACT:
The data synchronizer overcomes problems with mismatched recording and analyzing equipment and can be used for multiple channel recording. By preliminary analysis a reference point is located on the record signal and used to trigger the data processor. Each channel of the recorder is then played into the data processor using the data synchronizer to provide a triggering signal for the data processor. Each channel is thus able to be analyzed from the same time reference. The data synchronizer decodes the recorded three level digital signal during playback and provides an output synchronizing pulse to externally trigger the computer system. This pulse occurs at the same instant relative to the data recorded each time the tape is played back, regardless of the playback speed.
